To all whom t 'may concern Y Be it known that I, JAMES F. KUHN, a citizen of the United States residing at Easton, in the county of Northampton and State of Pennsylvania, have invented a new and useful Safety-Fastening for Jewelry, of which the following is a specification.

This invention relates to safety fastenings for brooches, or other similar articles of jewelry.

The object is to provide a fastening means, to be applied to the back of a brooch, buckle, or simi ar article of jewelry, which, when properly adjusted, will prevent the fastening pin from accidental dislodgement Y from the goods to which the saine may be applied, and in which the several parts Yof the improved device are permanently secured to the brooch or other article, so that it is impossible for them to become detached therefrom and lost. Y

Another object is to provide means for locking the fastening in into engagement with the said goods, w lich may be readily operated by thethumb and finger of the wearer, without the necessity of seeing the device, and which, when applied, is entirely hidden from view by the brooch or other article of jewelry.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accomanying drawing forming part of this speci cation; it being understood that while the drawing shows a practical form of the invention, the latter is not confined to strict conformity therewith, but maybe changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention, as specil'ically pointed out in the claims appended hereto.

In the drawing, in which like reference numerals designate corresponding parts in each of the several liguresi Figure 1 is a side elevation of the improved device shown attached to a brooch.

Fig. 2 is an elevationV of the rear sideV openposition.

Fig. 4 is an enlarged detail sectional viewY of the operatin end of the pin, v.F ig. 5 is a etail sectional view on the une 5 5 of rig. 1.

. spaced ears 2, preferab y located adacent to one end of the said body and secured thereto in any desired manner. In the present instance, the ears are shown as composed of a single piece of metal havin a connecting member 3, which is solder or otherwise secured Yto the body.

Located adjacent the opposite end of the body l and in spaced relation to said ears 2, there is provided a tubular lice er 4 su ported by a post 5, which is lili) dered or otherwise secured to the said body 1. The keeper l has a tubular bore or passageway 6 formed entirely through the same, the Yaxisrrof which extends longitudinally of the body member 1, and in alinement with the said ears, and isspaced away from the rear or innerrface of the body member 1, for a purpose to be described.

Mounted for pivotal nioveinentfbetween the ears 2 is a rockable sleeve 7 provided with an odset lug 8, which is adapted to lit freel between the said ears 2, and to be loose y held therein by a pivot 9 passed through appropriate registering perforations formed in the lug 8 and the ears 2, said pivot, bein properly upset at its ends to retain it in ace. The lug 8 is provided on the side a jacent to the post 5 with a shoulder 10, which is adapted, when the sleeve 7 is brought into parallelism with the body 1, to abut against the part 8 of the ears 2, and form a stop to arrest Vfurther movement of the sleeve 7 in that direction. The remaining portion ofthe lng 8 is formed concentric with the axis of the pivot 9, 'and therefore permits the ready rocking movement of the sleeve 7 in the opposite direction, as illustrated in Fig. 3.

Arfastening in 11 formed of any suitable imetal is a opted to traverse the sleeve 7, and is of a length approximately equal;

ewise so pin 11 is provided at one end with the usual penetratiir point 12, and has secured on its other termmal an operating head 13, which is preferably, though not necessarily, milled to facilitate the turning of said pin Within the sleeve 7, for a purpose to be described.

A laterally disposed entrance opening 14 is provided on the inner end of the tubular keeper 4, and is formed by cutting away a portion of the metal thereof located adjacent to the body member 1, as indicated in Fig. 5, said openingextending from the inner end of the tubular keeper 4 to the adjacent inner face of the post 5, which post, in the present form is shown as being of less thickness than the length of the tubular keeper 4, the latter projecting from both sides of the post. This entrance opening 14 is for the purpose of permitting the point 12 of the fastening pin 11 to enter the bore of the tubular keeper 4, and to be afterward projected farther into the keeper 4 in a manner to be explained. The fastening in 11 is threaded, as indicated at 15, adjacent to the head 13 for a distance equal to the length of the rocking tubular sleeve 7, which in turn, is interiorly threaded at 16 for a distance equal to half its length and extending from the outer end thereof to its approximate center.

The outer diameter of the threads 15 is equal to the diameter of the fastening pin 11, and thus a shoulder 17 is in effect provided at the beginning of the threaded portion 15, which shoulder is adapted, when the pin is unscrewed from the tubular sleeve 7, to come in contact with the threaded portion 16 of said sleeve 7 and to prevent the further unscrewing of the pin 11. 0n the other hand, the head 13 abuts against the adjacent outer end of the tubular sleeve 7, and prevents further longitudinal movement of the pin 11 through the sleeve 7, when the said ead is turned in the appropriate direction to screw the pin 11 into the sleeve 7.

In Fig. 3 of the drawing, the device is shown in a position to be applied to the a parel of a wearer, the shoulder 17 of the pm 11 abutting against the threads 16, and the said pin together with the sleeve 7 being rocked upon the pivot 9 to remove the point of the pin away from the tubular keeper 4 for the purpose of passing the point through the goods to which the brooch is to be applied. The sleeve 7 and pin l1 are then rocked upon the pivot 9 until the shoulder 10 bears against the member 3 of the ears and upon further pressure of the pin to cause a fiexing of the same, as illustrated in dotted lines in Figs. 1 and 5, the point l2 of the pin is brought around the end of the keeper to a position opposite the laterally disposed entrance opening 14, when the same may be sprung through the opening into alinement with the bore of the keeper 4. W'hen the pin 11 is in the position just described, the point 12 is free to escape the adjacent face of the post 5, and to freely pass within said entrance opening 14. The shoulder 10 of the lug 8 bearing against the member 3 Will cause an outward pressure of the pointed end of the pin 11 against that Wall of the keeper 4 remote from the entrance opening 14. This pressure, together with the pressure of the goods, contained between the fastening pin 11 and the body member 1, will serve to prevent, at all times, the accidental displacement of the point 12 from the keeper 4, prior to the longitudinal movement of the pin 11.

After the brooch has been applied in the manner described above, it is only necessary to turn the head 18 in a direction to screw the pin 11 through the tubular sleeve 7 until the head 13 abuts against the adjacent end of the sleeve 7, when the point 12 of the pin is projected longitudinally beyond the end of the entrance opening 14, and thus it is impossible to remove the brooch from its applied position, until the reverse movement of the pin 11 has been effected. By reason of the construction of the sleeve with the threads therein extending only a portion of the length thereof andthe threads on the pin extending a distance equal to the length of the sleeve permits the adjustment of the pin to engage in the keeper, and when so engaged, the threads of the pin are entirely concealed Within the sleeve to avoid the possibility of the threads engaging with the fabric and thus damaging the same.

The device, when applied in position upon the clothes of a wearer, is entirely hidden from view by the body member 1 of the brooch, and it Will be seen that the same may be readily removed therefrom by a simple unscreiving action upon the head 13, and the proper manipulation to free the point 12 from the tubular kee er 4, throu h the entrance opening 14, an it `will be urther seen that all of the parts of the device are permanently xed to the brooch 1, so thanL there is no danger of separation.

From the foregoing, it will be seen that a simple, cheap, and durable fastening means for various articles of jewelry has been devised, which may be manufactured at a 10W cost, and which effectually prevents the accidental displacement thereof from its applied position.

It Will be understood that other mechanical means than the specific means shown for moving the p'm longitudinally through the sleeve will be suggested to the mind of a skilled mechanic.

What is claimed is 1. In combination With a body member, a tubular keeper in spaced relation thereto, said keeper having a lateral entrance openmg, a longitudina ly disposed tubular sleeve threaded mteriorly, means for pivoting said longitudinally disposed tubular sleeve to the body member in spaced relation to said keeper whereby said sleeve may be rocked, and a fastening pin having threaded engagement at one end with the pivoted sleeve and an operating head at one end for turning the pin through the sleeve to Cause the point thereof to enter through or to be withdrawn from the entrance opening of the keeper, the. threads on the pin being entirely concealed within the sleeve when said pin engages the keeper.

2. .ln combination with a bodyr member, a tubular keeper in spaced relation thereto, seid keeper having an entrance opening, a sleeve, which in its normal position is in alinenient Twith the tubular keeper, means for pivoting said sleeve to the body member in spaced relation to said lreeper, whereby said sleeve may be given a rocking movement, said sleee being threaded for a portion of its length, a fastening pin havin one end threaded for a. distance substantially equal to the length of the sleeve, and an operating head on the pin beyond the threaded portion for turning the pin through the sleeve to cause the pointthereof to enter through or be Withdrawn from the entrance opening of the keeper, the terminals of the threads on the pin and in the sleeve being coaetive to limit the adjustment of the pin in one direction, while the head limits the reverse movement of said pin, the threads on the pin being enoples oi this patent may be obtalnefl for ve tirely concealed Within the sleeve when said pin is engaged in the keeper.

3. Fastening means for an article of jewelry comprising a pair of spaced ears formed on the back of the article, a sleeve having a laterally odset lug directed toward the body of the article and mounted for pivotal movement between said ears, said offset lug having a stop shoulder to limit the inward swinging of the sleeve, said sleeve being interiorly threaded approximately one-half of the length of its bore, keeper mounted upon the body in spaced relation to the sleeve and in longitudinal alinenient therewith and having an entrance opening in the inner end, and a fastening pin mounted in the sleeve and having e manipulating head at one end and threaded, adjacent to said head for a distance substantially equal to the length of the sleeve, and pointed at the other end, said pointed end being adapted to be passed through the lateral entrance opening and then projected through the tubular keeper or Withdrawn therefrom upon the proper turning of the said head.

In testimony, that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two Witnesses.
